I was outside of my home. I was looking upward to watch stars as I do it every night. It was 11:09 o'clock. 'Two' bright stars were there at the right side of Scorpion constellation. Suddenly one of them disappeared.I was shocked. I searched for if any aeroplane or any satellite was there. But I found nothing. There was no other light moving as that happens for aeroplane. The star like thing just disappeared.
